Oh crap.
All the easy answers are exhausted ....
Drop me a personal email and lets figure this out.

I already installed the dev packages "fftw3"& "fftw3-dev"& "libfftw"
Are the header files in the include directory?

Hi, I'm running into some issues linking against libraries. I'm running a
"console-image" Angstrom on the Beagleboad and I've been adding packages as
necessary to support compiling code directly on the board.
To support building packages on the BB, I bitbaked "package-native-sdk" and
"pkg-config" and installed those packages with all the other dependencies as indicated by
opkg: gcc, libgcc, automake, perl, .... etc.
Now I'm trying to compile a program natively that links against fftw3 library so I
bitbaked and installed the fftw3 library: the libfftw3, fftw3, and fftw3-dev. Now to
link to fftw3 I added the "-L /usr/lib -lfftw3" flags for link but i would get
the error message
cannot find -lfftw3
collect2: ld returned 1 exit status
I also tried using "pkg-config --libs fftw3" in my Makefile and I still get the
same error message. I don't know why GCC can't seem to find the library especially that
pkg-config and ldconfig have links to the library. The following are outputs from
pkg-config and ldconfig
ldconfig -v | grep fftw
libfftw3.so.3 -> libfftw3.so.3.2.2
libfftw3f.so.3 -> libfftw3f.so.3.2.2
pkg-config --list-all
fftw3f FFTW - fast Fourier transform library
fftw FFTW - fast Fourier transform library
fftw3 FFTW - fast Fourier transform library
it seems to me that everything is in order but i'm probably missing something
... any help would be greatly appreciated. thanks
I bet you need the dev packages.
fftwf-dev and/or fftw-dev
